Summary:PROBLEM TO BE SOLVED: To optimally form an entire microscopic device in terms of resolution, the depth of focus and stereoscopic effect. SOLUTION: The exit pupil AP of an objective lens OB is divided to two crescent shapes by a DMD(digital micro mirror device) mirror in the vicinity of the exit pupil AP, and an observed subject is observed at a variable solid angle. Simultaneously, an observation aperture is utilized to the maximum, and the center of gravity of the crescent shape is adjusted to obtain high microscopic resolution. By alternately feeding light with time limit to a left eye and a right eye at the upper part of flicker frequency, the observed subject with transmitted light and irradiating light is observed.
